Is anyone looking at these pages? Let me know (It is too late to send input on when the next exam should be, it's now scheduled for Nov 20. But you can add anything you'd like to tell me ...)

Nov 4: Section 5.1. The lecture demo site on the theremin has a link to more theremin references, including audio samples, and this is a movie of a theremin player.

Nov 6 Sections 5.1, 5.2. Spectra of modulated signals

Nov 11 Sections 5.2, 5.3. We showed an old synthesizer, learned the meaning of decibels (at least, of "3 dB"), looked at the signal produced by FM by feedback.
